Sustained engine bay heat breaks down the internal winding insulation and epoxy seals on aging coils, causing internal arcing, high secondary resistance, and erratic spark. Combined with electrode erosion on high-mileage spark plugs, the \u003cstrong\u003e5.4L Triton 3V\u003c\/strong\u003e Modular engine experiences hesitation, rough idling, fuel wash, and loss of towing power under cylinder load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis refresh package replaces compromised hardware with heavy-duty coil packs and genuine \u003cstrong\u003eSP509\u003c\/strong\u003e Motorcraft platinum spark plugs. The direct-fit coils utilize high-dielectric silicone boots and high-conductivity copper windings designed to resist thermal breakdown and prevent voltage leak to the cylinder head. The platinum-tipped plugs maintain a stable spark gap under high combustion pressure, ensuring complete fuel burn, smoother idle, and consistent cold-start ignition.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e8 Ignition Coils (OE Spec Boot and Connector)\u003c\/li\u003e\n  \u003cli\u003e8 Motorcraft Platinum Spark Plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2009-2010 Ford F-350\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e5.4L Triton 3V V8 \/ P356\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e300 hp \/ 365 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eFD509, SP509, EBC1519, 26C1045, SKIC501, CFD509, C1659VC, 2IGC0157, 673-6200, 52-2071, C1659SPEC, 2-50107, 140033E, 140033EB, 140033EB-8, 140033EK, 140033EK-8, 1IC486, 50107, 36-8180, 5096, 2505-484845, IGC0117, E509, C1659, 022150470A, GN10233, 48874, U5260, C-800, C1659-8, C1659DLGKIT, 8L3Z12029A, 921-2007, 921-2066, 5C1716\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009 Ford F-350 Super Duty 5.4L V8\u003c\/li\u003e\n  \u003cli\u003e2010 Ford F-350 Super Duty 5.4L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the P356 F-350?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2009-2010 Ford F-350 equipped with the \u003cstrong\u003e5.4L Triton 3V\u003c\/strong\u003e engine. \u003cstrong\u003eThis kit does not fit 6.8L V10 or 6.4L Power Stroke diesel applications.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eShould spark plugs and coils be replaced simultaneously?\u003c\/h4\u003e\n\u003cp\u003eYes, pairing fresh plugs with new coil packs prevents worn plug gap resistance from overloading and prematurely burning out new ignition coils.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle the high-thermal demands of commercial work and heavy towing, this ignition kit maintains steady spark energy across severe duty cycles, ensuring your Super Duty retains its rated haul capacity.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67561492807928,"sku":"DS-ET1HCOZ8P","price":233.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-platinum-spark-plugs-for-ford-f-350-2009-2010-5-4l-1.jpg?v=1790964634","url":"https:\/\/performancechiptuning.com\/de\/products\/ignition-coil-platinum-spark-plugs-for-ford-f-350-2009-2010-5-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
